88    o verification/lab_sea
89      - added description of sea-ice model
90      - added missing matlab routines

92    
93    release1_p8
94    o verification/natl_box:
95      updating new external_fields_load routine
96    o New package: pkg/seaice
97      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
98      The sea-ice code is based on Hibler (1979-1980).
99      Two sea-ice dynamic solvers, ADI and LSR, are included.
100      In addition to computing prognostic sea-ice variables and diagnosing
101      the forcing/external data fields that drive the ocean model,
102      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
103      The implied surface heat flux is then stored in variable
104      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
105      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
106      non-local transport term.  Because this call precedes model
107      thermodynamics, temperature under sea-ice may not be "exactly" at
108      the freezing point by the time theta is dumped or time-averaged.
109      N.B.: fairly large differences in accuracy occur across
110            different platforms/compilers; comparison between
111            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
112            generated output gives:

120    
121    release1_p7
122    o GAD:
123      - generated new common blocks to account for call of
124        same gad routines with differing traceridentities

127        (Department of Futurology)
128      - parameter lists to gmredi_?transport: added tracerIdentity
129      - added new key indices to tamc.h
130    o external_fields_load:
131      - added this routine to TAF list
132      - needed to make some common blocks global and additional storing
133        along the same lines as exf package (checkpoint_lev?_directives.h)
134    o exf:
135      updated external forcing package
136      - bug fixes carried over from ecco-branch

145      the exf (and cal) package instead of the
146      external_fields_load routine (cf README file).

276      (mainly thermodynamics.F)
277    o New store directives for multi-dim. advection schemes

312                        bi,bj loop
313      mdsio_writelocal - same as mdsio_writetile except works for local
314                         arrays
315      write_local_r? - higher-level wrapper for mdsio_writelocal
316      Controlled by diagFreq. Defaults to zero (ie. no dumps)
317      Example given at end of mom_vecinv.F that dumps some local arrays.

321      or genmake -DISABLE ...
322    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F

340    o bug fix in gmredi_slope_limit for ldd97
341    
342    checkpoint40pre5
343    o proper initialization of Adams-Bashforth time stepping
344      + uses forward step for very first step of model (iter=0)
345    o re-generated *all* output since almost all output is modified by this
346      change (sorry but we've been putting this one off for about 2 years)
347      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
348        *not* regenerated since they are already out of date and I don't
349        want to create the impression that they are suddenly working.
350    o removed KAP stuff for DEC's
351    o modified/added many .cvsignore files in */code and */input
352    o added new expt "solid-body.cs-32x32x1"
353      + this uses an alternative form of ini_curvilinear_grid.F which
354        is not necessarily any better than the current one...
355    
356    checkpoint40pre4
357    o added re-initialisations of utrans,vtrans,rtrans in
358      calc_common_factors which are crucial for TAF.

371    o Added gradient check package
372    o Added routines for passive tracer handling
373    o Added carbon sequestration sensitivity experiment
374    
375    checkpoint39
376     o Modifications and fixes to support TAMC
377       (mainly missing or wrong directives)
378     o Corrected common blocks when fooling TAMC to produce adjoint I/O
379       in addummy_in_stepping
380     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
381     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
382     o Included following packages:
383       cal: calendar
384       exf: external forcing
385       ecco: essential routines to control use of cal, exf
386             (NB: this is not the full ECCO environment)
387     o disabled some packages by default in genmake
388    
389    checkpoint38
390     o see notes_c37_adj.txt
391     o corrected wrong layer index in external_forcing_t
392     o replaced the_main_loop/forward_step by the_main_loop
393     o removed forceoutput from write_state
394       (replaced criteria for initial/final state)
395     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
396    
397    checkpoint37
398     o mdsio.F routine split and packaged in pkg/mdsio
399       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
400        used unless genmake -disable=mdsio)
401     o allow a more precise surface-geopotential gradient for the atmosphere
402       taking into account the change in space of Alpha (=1/rho) at the surface.
403     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
404       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
405     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
406       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
407       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
408     o Time-Average diagnostics defined as a pseudo package "timeave".
409     o pickup files : old pickup (before c35) did not work with new code (c35
410       and after) unless activating 2 commented lines in initialise-varia.
411     o Non-Hydrostatic pickup file Pb fixed.
412     o bug with Rigid-lid version (since c35) fixed.

422     o allows staggered time-stepping
423     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
424     o added bottom drag (linear + quadratic)
425    
426    checkpoint34
